The Astolat Dollhouse Castle is an $8.5 million dollhouse filled with incredible miniature art and valuables. When you break it all down, the dollhouse is the most expensive piece of real estate in the City, costing over $2,000 per square inch.

Built by miniaturist Elaine Diehl, the dollhouse took 13 years to make and was completed in the 1980s, using handcraft techniques to make each of the 10,000 miniatures inside the 29 rooms of the castle. Goldsmiths, glass blowers, silversmiths, carpenters and more were commissioned to make the pieces, which include a miniature harpsichord, chandeliers, oil paintings by renown artists, fireplaces (with faux flames), vintage automobiles, and readable books. There’s even miniature rolls of toilet paper, the “smallest antique Bible in the world,” and an antique Torah. In fact, there are over 30,000 pieces available to decorate the dollhouse but only about one third are on display at a time. The castle is 9 feet tall, has seven levels (including hidden passageways), and weights over 800 pounds.
